The purple whale is a massive creature that lives to the north of Hillys, beyond Black Isle. It swims around just beyond the barriers set up by the Alpha Sections.

This whale is bigger than a cargo ship and its skin is of an orange color with lighter patterns on its back. Its belly is completely white. Just like its cousin, the Megaptera borealis, it sometimes breaches out of the ocean in an acrobatic jump (though its tail remains submerged), but otherwise remains underwater. Jade can be alerted to its presence by witnessing it expulsing air from its blowhole, creating a jet of water or mist above the water.

It is based on the real-life humpback whale, the Megaptera novaeangliae.
